FIRE-EXTINGUISHING APPARATUS FOR MOTOR VEHICLES.

Application filed October 3, 1922. Serial No. 592,073;

The object of my invention is to provide an apparatus for motor vehicles which can be utilized in connection with any suitable fluid fire extinguishing medium for extinguishing a fire in an automobile; to provide means whereby the device will operate automatically; and to provide means for readily connecting the device with a container of fire extinguishing fluid, such as carbonic acid gas; and to provide a device which can be readily and quickly put into operation, and which will not damage the mechanism of the car in any way as a result of the application of the fire extinguishing medium. I attain these and other objects of my invention by the apparatus disclosed in the accompanying g drawings, in which-- Figure 1 is a longitudinal section through a portion of an automobile showing my apparatus in side elevation;

Fig. 2 is a transverse section throu h the automobile on the line 2-2 showing t 1e op- 'eration of the appliance containing the fire extinguishing fluid;

Fig. 3 is a transverse section on line 3-3 of Fig. 1, my invention being shown in section and the automobile engine being shown in dotted lines;

Fig. 4 is a detail view, partly in section and partly in elevation, of the joint connection of conduits 5 and 4;

Fig. 5 is a section on line 5--5 of Fig. 1; and

Fig. 6 is an enlarged detail view of the discharge head having the fusible member 19 for automatic operation of the extinguisher.

Like numerals indicate like parts in each of the several views.

Referring to the accompanying drawings, I provide a suitable container 30f the fire extinguishing fluid, such, for example, as carbonic acid gas, this container being removably mounted between spaced clips 2 and having a flexible discharge tube 4 which is detachably connectible by means of a suitable connection 6 with the threaded end of conduit 5. Conduit 5 is suitably suspended by means of clips 7 which also engage a suitable supporting rod 8 arranged under the hood and above the engine in an automobile, substantially as shown in Figs. 1 and 3. Conduit 5 is rovided with short discharge pipes or nozz es 9. It is also provided with a branch conduit 10 which opens into a suitable casing 11, which enga es over, or artly over, the carburetor of theiengine, su stantially as illustrated in Fig. 3. I also provide a branch conduit .13 in ponnection with a pipe 5 through connecti "n 12. Branch conduit 13 extends rearwaZdly under the foot-board and is provided ith an upwardly extending portion 15 di posed under the seat of the automobile. "Conduit 13 is provided with suitable discharge months or plugs 16, as illustratedin Figs. 1 and 5.

In order that the device may operate automatically when a fire occurs in the automobile, I may provide nozzles or discharge pipes 9 with caps 17 which hold a fusible plug 19 over the mouth of nozzle or pipe 9, but which will melt at a predetermined temperature to release the fire extinguishing fluid through the opening 18 in the cap 17. To operate the invention the fire extinguishing gas is released by opening the valve 20 allowing the fire extinguisher to" flow through tube 4 into conduit 5, and thence through the discharge nozzles 9 and 16. If, however, it is desired that the operation of the extinguisher shall be controlled automatically when a certain temperature is reached, instead of manually, the several nozzles 16 and 9 will be provided with the caps 17 and fusible plugs 19 which normally hold those nozzles closed but which when the temperature rises to the danger point will melt the fusible plugs and release the fire ex tinguishing fluid. As the tube 4 is detachably connected with the pipe 5 the contents of the container 3 may be used for other pur poses aside from its primary use as a fire extinguishing appliance. The connections are of air-tight character to insure perfect operation of the apparatus.

What I claim is:

A fire extinguishing system for automobiles, including a container of'liquid carbon valve controlled outlet, means for detachably supporting said container. on the automobile,

' with its valvein reach of the drivers seat,

sure indicator connected in the outlet from 10 the valve, a casing substantially enclosing the carbureter and a conduit opening into said casing and communicating with said first named conduit, for supplying the carbonic acid gas under pressure for fire extinguish- 1 ing purposes substantially asset forth.
